Checkout page is not working on IE (magento 2.3.3)

The checkout page didnt work on IE. The page was loading forever.
I found a lot of solutions and some reference links:

1. Disable Full Page Cache (i think this will turn off fastly cache as well)

2. Increase cookie life time on System >> Configuration >> General >> Web >> Session Cookie Management >> Cookie Lifetime
